Specification of Letters Patent.

Patented Aug. 9, 1921.

Application filed October 17, 1919. Serial No. 331,288,

To all whom it may concern Be it known that I, EDWARD M. HEYLMAN,

- a citizen of the United States, and a resident of South Bend, in thecounty of St. Joseph and State of Indiana, have invented certain new anduseful Improvements in Flows; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This inventionrelates to improvements in plows and more particularly todepth adjusting or regulating means for power-lift tI2LCtO1-(lI'LWI1plows, one object of the invention being to provide depth adjustingmeans which shall be so constructed that no part of the same willproject appreciably above the plow frame, whereby said adjusting orregulating mechanism shall be adaptable for use with a plow to be workedin an orchard where upwardly projecting adjusting levers on a plow wouldinterfere with the plowing operation by conflict with the limbs oftrees.

With this and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a plan view of a plowembodying my improvements; F ig; 2 is a side elevation; Fig. 3 is anenlarged section on the line 33 of F ig. 1, and Fig. 4 is a sectionalview showing one of the levers 25 and its mounting.

1 represents a plow frame comprising beams 2, 2, 3 provided at theirrear ends with standards 4, to which plow bases 5 are secured. Theforward ends of the beams 2, 2 are bent downwardly as at 6 and arespaced apart by a cross bar 7 and the rear ends of the beams are spacedapart by braces 8.

Bearing brackets 9-10 are secured to the respective beams 2-2 andprovide mountings for a land-wheel axle 11, the spindle portion enteringthe hub of a land wheel 12. A bearing sleeve 13 is secured to the crankaxle 11,said sleeve being provided with lugs 14 clamped to said axle 11and preferably also keyed thereto. A furrow-wheel crank-axle 15 ismounted in the bearing sleeve 13 and its spindle portion enters the hubof a furrow wheel 16. An arm 17 is secured to the crank axle l5 andcarries a member 18 to be engaged by an arm 19 on one of the lugs of thebearing sleeve 13, said arm being, in effect, thus secured to the crankaxle 11. When the plow frame is bemg raised and the crank axle 11 causedto turn, engagement of the arm 19 with the member 18 on arm 17, willcause the crank axle 15 to turn also.

Clevises 20 are adjustably secured to the downwardly bent forward endsof the beams 2-2 of the plow frame, and with these clevises, a hitch bar21 is connected. A draw bar 22 for attachment to a tractor, is connectedwith the hitch bar and an adjustable brace 23 is provided for said drawbar.

A shaft 24% is mounted in suitable bearings 2-flon the brackets 910,said shaft being disposed transversely of the plow frame and projectingbeyond the beams 2-2 thereof. Near respective ends of the shaft 24,levers 25 are loosely mounted on the bearings 24', each of said leversbeing made, intermediate of its ends, with a hub 26 mounted on the shaftand the lower arm of each lever is bifurcated and carries a roller 27 toengage the crank of the adjacent crank axle. The upper arm of each lever25 carries an internally threaded sleeve 28,-said sleeve being swiveledor pivotally connected to the lever. Standards 29 are connected with theforward portion of the frame, preferably to the clevises attached tosaid frame, and are braced as at 30. Sleeves 31 are pivotally supportedat the upper end of the standards 29, and in these sleeves,approximately horizontal shafts 32 are mounted to turn freely, but saidshafts are prevented from longitudinal movement by means of collars 33.lhese shafts are threaded, as at 34c, and pass through the threadedsleeves 28 at the upper ends of the levers 25, and the forward ends ofsaid shafts are provided with crank handles 35 whereby they may bemanually operated.

It will be apparent that by turning the shafts 32, the levers 25 will beturned on their pivotal connections with the shaft 2A and as the rollerscarried by the lower ends of said levers bear upon the cranks of theaxles 11 and 15, the plow frame will be raised or lowered more or lessto regulate the depth which the plow bases carried by said frame willenter the ground and thus the plow may be adjusted or regulated for animportant consideration in an orchard. plow.-

'Having fully described my invention what I claim as new and desire tosecure byLetters-Patent, is I y 1. In a plow, the combination with aplow frame, a plow base carried thereby, a crank axle, and wheels, of alever pivotally mounted on the plow frame and having its lower enddisposed overthe crank arm of the axle without direct connectionthereto, an approximately horizontal manually operable shaft havingthreaded and-pivotal connection with said lever, and a support on theplowframe for said shaft. i

2. In a plow, the combination witha plow frame, a plow base carriedthereby, a crank" axle,and wheels, of a lever pivotally mounted on theplow frame and having its'lower end disposedover the crank arm. of saidaxle without direct connection thereto, an

, internally threaded sleeve pivotally connected with said lever,anapproxi-mately horizontal manually operable shaft ,having a threadedportion passing through said sleeve, a support on the frame, and meansconstitutmg a swlveled connectlon between I said shaft and said support.

' lever. r

3. In a plow,the combination with a plow frame, a plow base carriedthereby, a crank axle, and wheels, of a lever having pivotal connectionbetween its ends with the frame, said lever having its lower enddisposed over the crank arm of said axle without direct connectionthereto, an internally threaded sleeve having pivotal connection withthe upper end of said lever, a standard on the frame, a sleeve pivotedto said standard, and a manually operable shaft mounted in saidlast-mentioned sleeve and having a threaded portion passing through theinternally threaded sleeve at the upper end of said 4. In a plow,

two independently movable crank axles, and wheels on said crank axles,of. levers pivot-v ally mounted between their ends at respective sidesof the frame, said levers carrying rollers at their lower ends toengagethe crank arms of the respective :axles, internally threadedsleeves pivoted-to the upper ends of saidlevers, standards near the forthe combination with a plow frame, a'plow base carried thereby,

ward end of the frameat respective sides thereof, sleeves pivoted tosaid standards, and manually operableshafts mounted to turn in saidlastimentionedsleeves and having threaded portions passing'through thesleeves at the upper ends of: said levers.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses. i
